In obese adults, excess visceral fat and insulin resistance are independently associated with incident prediabetes and type 2 diabetes, whereas general adiposity markers (BMI, total body fat, abdominal subcutaneous fat) are not.

If you are obese, your total weight or BMI is not the best predictor of your diabetes risk. Instead, focus on markers of 'dysfunctional adiposity': visceral fat (belly fat), insulin resistance, and liver fat. These specific factors drive the transition to prediabetes and diabetes, whereas general fat mass does not. Monitoring visceral fat and insulin sensitivity is more clinically relevant than tracking BMI alone.
